Title:
CHEMICAL LIQUID INJECTING CONSTRUCTION METHOD AND GROUND STRUCTURAL BODY
Document Type and Number:
Japanese Patent JP3957407
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently improve ground by injecting chemical liquid, dynamically changing injection speed or injection pressure in viscous soil ground, and generating many short split dikes in a design area.
SOLUTION: An injection pipe 1 is passed and inserted through/into viscous soil ground 7 such as Kanto loam, Kuroboku soil, marine clay and alluvial silt, a driving source 2 of a pump 3 is controlled by a control device 6 on the side of the ground and chemical liquid 5 within a tank 4 is injected by changing injection speed and injection pressure to various kinds of waveforms. Injection speed, injection pressure, pitch of waveforms, amplitude and periods are properly selected according to the object viscous soil ground 7 and nature of chemical liquid. Development of the split dikes 8 is prevented by dynamic changes in injection speed and injection pressure, many short split dikes 8 are generated within a design area, chemical liquid 5 is efficiently injected according to a design and a ground structural body 9 can be efficiently formed on the viscous soil ground 7.
